Now research performed by two San Francisco-based scientists, Dena Dubal of the University of California, San Francisco, and Lennart Mucke of the Gladstone Institutes, suggests that KL-VS might have other searing properties.

Because they are studying the aging process, Dubal and Mucke wondered whether KL-VS somehow held back the decline in mental abilities as one gets older.

Instead, they found something more startling. Regardless of one's age, it seems that the presence of KL-VS might actually boost IQ by as much as six points.

The researchers worked with 220 people, aged between 52 and 85. They examined their abilities in such areas as language, memory, attention, and visuo-spatial awareness.

They discovered that those who performed best, regardless of their age, enjoyed KL-VS. Moreover, research done by other teams threw up similar conclusions, hence expanding the sample size to 718.

It's true that none of these scientists measured general intelligence, so the idea of the six IQ points difference is their own estimate. However, previously discovered genes that are thought to have an influence on IQ were said to affect it by only half a point.

More Technically Incorrect

Though the klotho correlation might be coincidence, the scientists have continued to experiment with mice to see if they can genetically engineer corollaries.

Naturally, those who believe achievement and intelligence are everything will immediately wonder whether a drug could be created to make people smarter.

Indeed, given that one scientist this week said he thought humans aren't intelligent enough to be ready for an alien encounter, some might hope such a drug is developed speedily.

However, life has proved that being intelligent doesn't save one from bad decisions, mistaken judgments, nights in lap-dancing clubs that lead to arrests, and a vast gamut of behavior that might be attributed to the klotho-deficient.
